NASA’s James Webb Space Telescope presents a new perspective on 30 Doradus, or the Tarantula Nebula, a region well-known to astronomers studying star formation. Its nickname once came from its resemblance to the spider itself, but in Webb’s view the overall region takes on the appearance of a tarantula’s home—a burrow lined with its own spun silk. The Tarantula Nebula shelters thousands of young and still-forming stars, many revealed by Webb for the first time.

Today scientists from Stony Brook University’s School of Marine and Atmospheric Sciences (SoMAS) announced the culmination of a decade of science in a paper published in Frontiers in Marine Science, an international peer-reviewed journal, which describes a novel restoration approach used in Shinnecock Bay that has led to a 1,700 percent increase in the landings and densities of hard clams in that estuary, along with the expansion of seagrass meadows and the end of harmful brown tides – a result that brings the Shinnecock Bay back to its 20th Century glory for shellfishing and the result may serve as a shining example of a process to restore other estuaries around the country and world.

A study measuring mild depression, number of mental unhealthy days and number of anxious days in 10,359 adults 18 and older found those who consumed the most ultra-processed foods as compared with those who consumed the least amount had statistically significant increases in the adverse mental health symptoms of mild depression, “mentally unhealthy days” and “anxious days.” They also had significantly lower rates of reporting zero “mentally unhealthy days” and zero “anxious days.” Findings are generalizable to the entire U.S. as well as other Western countries with similar ultra-processed food intakes.

Citizen scientists spent thousands of hours observing trash on beaches in Washington and Oregon. Their surveys show that certain beaches, and certain areas of a single beach, are “sticky zones” that accumulate litter.

With the help of an acoustic camera that visualizes sound pressure, researchers from the University of Vienna investigated the calls of Asian elephants. The elephants emitted their low frequency “rumbles” mainly through their trunk or through their mouth and trunk simultaneously, and only seldomly through their mouth alone. This is the first study to conclusively demonstrate the combined oral and nasal call emission in a non-human animal. The study has recently been published in the journal “Animals”.
